"Why do they hate us?" Americans have been asking that question about Muslims since the 11 September 2001 terrorist attacks. And now a growing number of Muslims in America are asking the same question about their fellow Americans.

Nearly half of all Americans believe the US government should restrict the civil liberties of Muslim Americans.

27 per cent of 1,000 respondents supported requiring all Muslim Americans to register their home addresses with the federal government. In addition, 29 per cent believed undercover agents should infiltrate Muslim civic organisations.
